摘要: The capacitive touch panel, a high-resolution position sensor intended for computer displays, must be safe and inexpensive sense accurately in spite of electrical noise, dirt, or direct electrostatic discharge. implementation discussed uses quasi-static electric field, applied to semiconducting coating on the panel surface. A draws current from This can used compute position. If computation is performed properly, computed independent resistivity. electroquasistatic basis measurement with system implement it are described. >
